If you received a shock by just touching the box and not touching a bare wire, then you have a short. This could be a fire hazzard in the long run. If you can replace your wire with grounded wire then do so, but your breaker or fuse box will also have to be grounded. You should also replace any outlet with a GFI (Ground Fault) anywhere there is an outlet near a water source. If you are running your boxes in series, you can connect your GFI first in the series and every outlet downstream will be covered by the GFI.
If this sounds like a little more than you want to take on, maybe you might call an electrician. They are well worth the money when it comes to NOT burning down your house.
